Years ago while Josh was working with the Team CSC at the Dauphine Libere, he noticed one of their mechanics using the most amazing little chuck to manage the disc wheel inflation. Unlike anything he had seen before, it was all metal and used a ‘lollipop’ lever on the side to lock onto the valve stems in disc wheels. The mechanic explained that these were made in Japan and were coveted by all the Euro-Pro mechanics due to their scarcity. So Josh set out to improve the design and make it available to cyclists everywhere.

  1. Matthew Grace

    Excellent product. Greatly simplifies connection of a presta style air pump supply to your bicycles’ inner tube fitting. Also has provided me with a very tight seal eliminating air leakage even under higher pumping pressures. Quick Side-Lever release ensures minimum loss of air pressure when removing from inner tube fitting.

    Great Fix for Annoying Screw-on Air Pumps!
